1. Solve for the value of x
Answer:
x = 18Explanation:
Line E B C Needs To Equal 180°Create An Equation3x + 5 + 3x + 4 + 3x + 9 = 180
Simplify Both Sides Of The Equation(3x + 3x + 3x) + (5 + 4 + 9) = 180( Combine Like Terms)
9x + 18 = 180
9x + 18 = 180
Subtract 18 From Both Sides9x + 18 − 18 = 180 − 18
9x = 162
Divide Both Sides By 9
9x / 9 = 162 / 9

JUST ANSWER CORRECTLY THE ANSWER 12 IS WRONG PLEASE GIVE THE RIGHT ANSWER
Answer:
Step-by-step explanation:
given tanB= 4/3
so sinB=4/5
n cosB=3/5
given BC=15
BA=BC*cosB
=15*3/5
=9
AC=BC*sinA
=15*4/5
=12
Triangle ABC and DBE are similar by AAA
DB= BA-AD
=9-3
=6
DB/BA=DE/AC
6/9=DE/12
DE=12*6/9
=8
Answer:
DE = 8
Step-by-step explanation:
ΔABC and ΔDBE are similar.
As they share the same angles, the sides are in proportion to each other.
Therefore, we can solve using ratios.
Tan trigonometric ratio
[tex]\sf \tan(\theta)=\dfrac{O}{A}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleGiven:
[tex]\sf \tan (B)=\dfrac{4}{3}[/tex]
Therefore:
[tex]\implies \sf \dfrac{DE}{BD}=\dfrac{AC}{BA}=\dfrac{4x}{3x}[/tex]
We know that BC = 15 and that AC : BA = 4x : 3x
Using Pythagoras' Theorem:
[tex]\implies \sf (3x)^2+(4x)^2=15^2[/tex]
[tex]\implies \sf 9x^2+16x^2=225[/tex]
[tex]\implies \sf x^2(9+16)=225[/tex]
[tex]\implies \sf x^2=9[/tex]
[tex]\implies \sf x=3[/tex]
Therefore,
⇒ AC = 4 · 3 = 12
⇒ BA = 3 · 3 = 9
Now we have found the length of BA, we can find the length of BD:
⇒ BD = BA - DA
⇒ BD = 9 - 3
⇒ BD = 6
As DE : BD = 4x : 3x and BD = 6 then:
⇒ 3x = 6
⇒ x = 2
Therefore, to find DE, substitute x = 2:
⇒ DE = 4x
⇒ DE = 4(2)
⇒ DE = 8
Remind me to never trust my gut.
Answer:
Step-by-step explanation:
Distribute the negative sign to turn the equation into pure addition. Then, change the denominator of the two fractions to the same thing.
Multiply 12/11 by 3/3
[tex]\frac{12}{11}*\frac{3}{3}=\frac{36}{33}[/tex]
Multiply 2/3 by 11/11
[tex]\frac{2}{3}*\frac{11}{11} =\frac{22}{33}[/tex]
Add them together now
[tex]\frac{36}{33} +\frac{22}{33} =\frac{58}{33}[/tex]

Divide. -24 divided by 7 Enter your question as a mixed number, in simplified form, in the box. Please hurry! Thank you :D
Answer:
-3 1/7
Step-by-step explanation:
The required simplified mixed number of -24 divided by 7 is -3 3/7.
To divide -24 by 7, the result is a mixed number in simplified form.
Divide -24 by 7:
-24 ÷ 7 = -3.428571...
Simplify the result as a mixed number:
To write the mixed number, we take the whole number part, which is -3, and the fractional part, which is the remainder after dividing.
The remainder is approximately 0.428571... (it goes on infinitely), but we'll round it to the nearest fraction for simplicity.
Approximately, 0.428571... is closest to 3/7.
So, the simplified mixed number is -3 3/7.

Rosa loves to run. She set a goal to run greater than 490 miles this year. To date, she has run 145 miles. If she begins to run 15 miles per week, how long will it take Rosa to reach her goal?
Write an inequality, using x as the variable, that represents this situation.
Answer:
Step-by-step explanation:
145+15x>490. subtract 145 from both sides
15x>345, divide both sides by 15
x>23
So she will need to run for more than 23 weeks to reach her goal.
y is inversely proportional to a*3. when y=10, a=2. a is directly proportional to x. when x=4, a=20. find the formula of y in terms of x
The first statement should be;
y is inversely proportional to a³.
Answer:
y = 0.64/x³
Step-by-step explanation:
y is inversely proportional to a³. This is;
y ∝ 1/a³
Thus, y = k(1/a³).
Where k is the constant of proportionality.
When y = 10, a = 2.
Thus; 10 = k(1/2³)
10 = k/8
k = 80.
Thus; y = 80(1/a³) - - -(1)
Also, a is directly proportional to x. Thus;
x ∝ a
So, x = ka
when x = 4, a = 20
Thus;
4 = 20k
k = 4/20
k = 1/5
Thus;
x = a/5
a = 5x
Put 5x for a in eq 1 to get;
y = 80(1/(5x)³)
y = (80/125) × 1/x³
y = 0.64/x³

the solution to a system of equations is (6, -3) choose two equations that might make up the system.
Answer:
y=x-9
y=2x-15
Step-by-step explanation:
To solve this we can just pick a random number for our slope and solve for the y intercept
For example lets say the slope is 1
we know that wehn x=6 y= -3 so we have the following equation
-3= 6+b
B is -9
which means one equation is
y=x-9
We can just repeat this same process
Let's say the slope is 2
-3 = 2*6+b
-3= 12
b= -15
which means taht
y=2x-15
